NOTE: As their name suggests hints are not exactly Dragon Ball Z: Ultimate Tenkaichi cheats, and are usually just simple (but very useful) tips on how you can unlock secret level, features, find hidden areas and such. Hopefully these will make playing Dragon Ball Z: Ultimate Tenkaichi even more entertaining.

Light Type Hero Unlocks
These are the skills, super attacks, and ultimate attacks unlocked through training under the various masters as a Light type Hero. You may only need to complete the indicating sparring sessions, or you may need to complete all sessions up to and including the indicated session. I personally compiled this information while doing the latter.

Heavy Type Hero Unlocks
These are the skills, super attacks, and ultimate attacks unlocked through training as a Heavy type hero in Hero Mode. The items were unlocked by going through each sparring session in order.

Unlockable Super and Ultimate attacks
These are attacks for created characters in Hero mode.
